What does x equal in this equation 2x plus 6 equals 7x-4?
hujkImproved anwser:2x+6 = 7x-42x-7x = -4-6-5x = -10x = 2
What is y equals x2 plus 7x plus 4 in vertex form?
You can get it to vertex form by completing the square: y = x2 + 7x + 4 ∴ y = x2 + 7x + (7/2)2 - (7/2)2 + 4 ∴ y = (x + 7/2)2 - 49/4 + 16/4 ∴ y = (x + 7/2)2 - 33/4
PQRS and equals 53 and equals 7x plus 4 what is the value of x?

What is the solution to the equations y equals 3x plus 4 and y equals 2 -7x showing key stages of work?
If: y = 3x+4 and y = 2-7x Then: 3x+4 = 2-7x So: 3x+7x = 2-4 => 10x = -2 => x = -1/5 By substitution: y = 17/5 Solution: x = -1/5 and y = 17/5
How do you solve 7x-2 equals x plus 4?
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
